2019 Audi Q5 Complaints

A failed (frozen) Turbocharger Wastegate Actuator. An engine warning light came on and engine had less power. It had to be replaced. There was a settled law suit for the same issue covering this item in previous vehicles settled in 2025.

My 2019 Audi Q5 has 23,300 city-driven odometer miles. The vehicle has been serviced and maintained per the Audi Service Manual, based on months in service, not accumulated mileage. The vehicle has been garaged both at home and at work. The vehicle has never been driven off-road. When driving, an “All-wheel Drive: malfunction! You may continue driving. Please contact Service” warning message sounded and appeared on the instrument panel. The malfunction was diagnosed by Audi Honolulu and another Audi repair shop as a Shift Fork Unit issue and/or Quattro differential failure, which needs to be replaced. Audi has has a Technical Service Bulletin for a similar problem for the Q5. Audi Honolulu and Audi America refuses to provide a goodwill repair citing the age of the Q5. While the vehicle is 7 years old, a Shift Fork or Quattro Differential should not fail at 23,300 miles, regardless of age. I have been told by both repair facilities that the Shift Fork Unit or Quattro Differential could...

The contact owns a 2019 Audi Q5. The contact stated that while driving approximately 30 MPH, the vehicle stopped and jerked, and the RED master warning light illuminated, and the message “Electrical Control Module” failure was displayed. On other occasions, while driving at undisclosed speeds, the turn signals and brake lights failed to operate as intended, and the message "Faulty Brake Light" was displayed. The vehicle was towed to the residence. The vehicle was taken to a dealer, where it was diagnosed, and determined that there was water trapped in the clogged sunroof drain, and the water leaked, and the control module was covered in water. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 95,000.

am writing to report a very concerning safety issue with my 2019 Audi Q5 and to request guidance on whether this may be covered under warranty or if my vehicle is experiencing a malfunction. On Saturday, while driving to an appointment, there was a bicyclist in the bike lane. Suddenly, the “Audi Presence” warning flashed red on my dashboard and the vehicle braked very hard on its own. I was not close to hitting the bicyclist and there was no imminent collision risk. The sudden braking was extremely frightening and could have caused an accident if a car had been behind me. It took quite a while for me to calm down and get my breathing back to normal after the incident. Then this morning, I received a dashboard warning that said: “Drive system: malfunction! Please contact service.” I am very concerned that this may be a malfunction of the automatic emergency braking or driver assistance system, especially after the unexpected hard braking incident. This feels like a serious safety iss...

Component: ENGINE AND ENGINE COOLING Summary: The turbocharger on my 2019 Audi Q5 failed prematurely. The initial check engine light and loss of performance began at approximately 48,000 miles, which is within Audi’s 4-year/50,000-mile powertrain warranty. The condition progressively worsened and the vehicle became difficult to drive safely in traffic due to reduced power and hesitation during acceleration. The turbocharger ultimately required complete replacement at 50,334 miles at a cost of $ 2511.20 This appears to be a premature failure of a major engine component. A sudden loss of power while merging or crossing intersections creates a safety concern. The vehicle has been properly maintained, is completely stock, and has never been modified. No warning was provided prior to the check engine light and rapid performance degradation. I am submitting this complaint because similar turbocharger wastegate failures have been documented in other Volkswagen/Audi vehicles using relat...
